Title: Production of certain hitherto undescribed acid esters of orthophosphoric acid and their salts
Inventor: ZENFTMAN HENRYK
IPC: C07F9/12
Filed: 1950-08-03
Abstract: The invention comprises p-tert. octyl-phenyl dihydrogen phosphate in the state of a solid crystalline compound, and p-tert. octyl-cresyl dihydrogen phosphates.  It also includes a process for the production of p-tert. octylphenyl dihydrogen phosphate and p-tert. octylcresyl dihydrogen phosphates which comprises gradually adding a quantity of water, which after allowing for losses by evaporation and entrainment, amounts to 2 mols. of water to 1 mol. of p-tert. octyl-phenoxy phosphoryl dichloride or p-tert. octyl cresoxy phosphoryl dichloride heated to a reaction temperature, removing the hydrogen chloride formed and keeping the reaction mixture fluid until the reaction is completed by control of the reaction temperature, the rate of addition of water being such that no aqueous layer accumulates. An indifferent gas, e.g. nitrogen, air or carbon dioxide may be passed through the mixture to assist removal of hydrogen chloride. Initially, the reaction temperature may be 85 DEG  to 90 DEG  C., and towards the end may be raised to 120 DEG  to 140 DEG  C. The acid phosphate may be converted into a salt by mixing it with an aqueous solution of a base in just sufficient water to enable the resulting salt to be obtained in the form of a paste.  Examples of the preparation of the two products are given.  The products are useful as frothing and coating agents (see Groups II, III and IV (c)).  p-tert. Octyl-cresoxy-phosphoryl dichloride is obtained by heating p-tert. octyl-cresol with an excess of phosphorus oxychloride in the presence of metallic iron.ALSO:Solutions of low concentration of the salts of p-tert octyl-phenyl dihydrogen phosphate and p-tert. octyl-cresyl dihydrogen phosphates are used for coating artificial fibres for spinning to import anti-slipping properties.  The preparation of such phosphates and their salts is described (see Group IV(b)).ALSO:p-tert. Octyl-phenyl dihydrogen phosphate and p-tert octyl-cresyl dihydrogen phosphates in small concentrations act as anti-corrosives for ferrous and non-ferrous metals, especially when associated with the presence of an oil.  Aqueous solutions of salts of such esters also confer non-slipping properties when a thin film is allowed to evaporate on a smooth surface for example metals, glass, tiles, smooth flooring materials and other smooth materials. The preparation of these compounds is described (see Group IV (b)).ALSO:p-tert. Octyl-phenyl dihydrogen phosphate and p-tert octyl-cresyl dihydrogen phosphates and their salts are suitable for use in froth flotation operations as collecting agents for mineral ores.  They float fluorspor, barytes, calcite, chromite, and ilmenite but not quartz.  They retain foaming properties between pH values of about 1.0 to 8.0.  The preparation of these compounds is described, (see Group IV (b)).

Title: Feeder Device for a Rotary Duplicator or Printing Apparatus.
Inventor: RITZERFELD GERHARD
IPC: B41L21/00
Filed: 1968-04-24
Abstract: 1,194,156. Printing machines; sheet feeder. G. RITZERFELD. 24 April, 1968 [28 April, 1967], No. 19431/68. Heading B6C. [Also in Division B8] In a rotary duplicator for printing on sheets with whole page duplication and on sheets of narrower width with line by line duplication an electromagnetically operated blocking device is withdrawn from the feed table of the machine when whole page duplication of sheets is required. As shown in the drawings a feed table 1, across which a card 2 to be printed and perforated is fed in the direction of the arrow A to the duplicating machine, not shown, in association with a perforator device, not shown, is mounted on plates 26 and 27. The card 2 is guided by a stationary guide rail 7, mounted on the table 1, and by a guide rail 8, pivotally attached to the table 1, and constituting a blocking member which, in the operative position, shown in Figs. 1 and 2, prevents copy sheets larger than the card 2 from being fed to the duplicating machine. Two controls 9 and 10, secured to the rail 8, permit the cards 2 to be fed only one at a time to the machine when the rail 8 is in its operative position. In the position shown in Fig. 1, the rail 8 is supported by cross-bars 11, 12 and extends above the table 1 through an aperture therein. The bars 11 and 12 and a stop member 13 are secured to a shaft 16 and the stop member 13 abuts an armature 17 of an unenergized solenoid 18 and is maintained in that position by a compression spring 19. Switch means 23, 24 control the energization of the solenoid 18 and the printing operation effected by the machine. Switch 24 controls the energization of the solenoid 18, whilst the switch 23 controls the printing operation as well as controlling the energization of the solenoid 18. When the switch 23 is closed whilst switch 24 is left open, the duplicating machine effects selective printing of cards 2 fed to the machine. Since the solenoid 18 is unenergized, the guide 8 is in the position shown in the drawings and any copy sheets fed to the feed table 1 having a width greater than the width of the cards will be prevented by the rail 8 from being fed to the machine. If the switch 24 is closed, as well as the switch 23, the solenoid 18 is energized and its armature rotates the stop member in the direction of the arrow B. The guide rail descends through the aperture in the feed table. It is then possible to feed copy sheets larger than the cards 2 to the duplicating machine for selective printing. If switch 23 is re-opened whilst switch 24 remains closed, whole page printing of copy sheets is obtained.

Abstract: Butter-like flavour is imparted to oleaginous foods such as margarine, shortening, cooking oils and salad oils by incorporation of a small quantity, e.g. below 100 parts per million, of a lactone of an aliphatic epsilon-hydroxy carboxylic acid.  Such lactones having 8 to 14 carbon atoms are preferred; a margarine which on heating develops the same flavour as butter when heated is obtained by incorporation of both a lactone having 8 to 11 carbon atoms and a lactone having 12 to 14 carbon atoms. Compounds capable of conversion in the food to the lactones, e.g. estolides of the appropriate hydroxy acids, may be employed.  The food may include lactones of aliphatic gamma-hydroxy and delta-hydroxy carboxylic acids in addition.  Butter aroma may be more nearly simulated by incorporation also of diacetyl, acetylmethyl carbinol and lower fatty acids.  The flavouring agent may, before incorporation in the food, be diluted with edible oil, e.g. ground nut oil, be mixed with anti-weeping and anti-spattering agents, or be emulsified in water.  Examples are concerned with incorporating oil preparations of the lactone of epsilon-hydroxy nonanoic acid and of the lactones of epsilon-hydroxy decanoic and dodecanoic acids into margarine. Specification 748,801, [Group IV (b)], is referred to.ALSO:Butter-like flavour is imparted to oleaginous foods, e.g margarine and shortenings, cooking oils and salad oils, cream and artificial cream, ice-cream, chocolate and confectionery, by incorporation of a small quantity, e.g. below 100 parts per million, of a lactone of an aliphatic epsilon-hydroxy carboxylic acid.
